logstash-role's Introduction

Role Name

Ansible Role to Install and Configure Logstash

Requirements

Java should be present on the nodes machines in order to run Logstash. On Debian OS family, python-pycurl and python-apt are required to deal with apt Ansible modules. The role already take care of these dependencies, however you can disable this behavior with --skip-tags=logstash_req.
